MATCHER-HEAD CU-TTER-VISE.

SPECIFICATION forming part of Letters Patent No. 427,517, dated May 6,1890.

Application filed February 21, 1890. Serial No. 341,320. (No model.)

To all whom, it may concern.-

Be it known that I, ANTHONY KROST, a citi zen of the United States,residing in Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Matcher-HeadCutter-Vises, of which the following is a specification.

The object of my invention is to produce a convenient device forsharpening matcherheads or for other similar purposes, all of which willbe fully and clearly hereinafter described and claimed, reference beinghad to the accompanying drawings, in which Figure 1 is a front elevationof avise made in accordance with my invention. Fig. 2 is a sideelevation. Fig. 3 is an enlarged sectional elevation, showing the meansfor tightening or releasing the portion for holding a matcher-head orother device for being operated upon. Fig. 4 is a top plan view of thegreater portion of the device, and Fig. 5 is a sectional elevation forillustrating that portion of the device over which the matcher or otherhead is put and held in place while being operated upon or sharpened.

In said drawings, 1 represents the base, to which is rigidly attached orformed in one piece with it an upright supporting portion 2. Through thesupporting portion 2 is an opening 3, (shown in Fig. 8,) through whichpasses a hollow cylindrical portion 1, having an interior screw-thread5, and at the outer end (rigidly secured to it or forming a part of it)is a hollow cylindrical portion 6, located thereon, so that the twotogether are in the shape of a T, or substantially so. Its obj ect is toreceive the shank 12 of the matcherhead holder which passes through it.The hollow T'portion 8 is provided on the part 7 with a screw portion10, (see Fig. 3,) which is adapted to screw into the interiorscrewthreaded portion 5. A washer 11, resting against a shoulder 011 thepart 7, prevents it from being drawn too far in to the part 4:. Thehandle 9 passes easily back and forth through the portion 8.

lVhen the several parts are drawn up tight by the handle 9, which passesthrough the tubular portion 8, and thereby tightens the screw portion10, one side of the shank 12 rests against a washer 13 and the otherside is held by the portion 6, substantially as shown in Figs. 2 and 3.

The matcher-head-holdi11g device consists of the shank 12, its headportion 14:, and a forwardlyprojecting tubular holding portion 15. It isprovided with an. interior screw-thread adapted to receive the screwportion 16, having a cone-shaped end 17, (see Fig. 5,) and at itsopposite end a handle 18. This handle 18 is omitted in Fig. 1. In thetop of the holding portion 15 is a hole, through which passes a shortplug 19, having a coneshaped inner end 20.

From the above construction it will be seen that by screwing the endportion 17 forward against the cone-shaped end 20 of the short plug 19the plug 19 will be forced outward, and thereby rigidly fasten acutter-head onto the portion 15, so that it will be held se curely whilebeing operated upon or sharpened. In operating with this vise thecutterhead is secured in place, as above mentioned, and the severalparts tightened, as hereinbefore described. It will be noticed that acutterhead can be held by this means in any desired position. It can bemoved either in the direction of the arrows or f, (shown in Fig. 1,) or,as shown in Fig. 4, it may be turned around on the shank 12 in eitherdirection, (shown by the arrows g or h,) so that any position may beobtained that may be required in sharpening or otherwise operating uponor repairing a cutter-head.

I claim as my invention- 1. In a matcher-head cutter-vise, thecombination, with a supporting-frame, of a screw portion, a handle foroperating it, an internal screw-threaded portion adapted to receive thescrew portion and provided with a hollow cross portion to receive theshank of the cutter-head-holding device for rigidly holding it in placein any required position, and a cutter-head holder having a means forrigidly securing the cutter-head thereto, sub

stantially as described.

2. In a matcher-head cutter-Vise, the comto screw into the portion 15,so that its conbination of a cutter-head holder, consisting ical endwill engage with the conical end of of the hollow cylindrical portion15, a short the short plug 19, for the purposes described. 10

plug 19, fitted thereto so that its cone-shaped ANTHONY KROST. 5 endwill project down inside, and a screw Witnesses:
